1. Turn on the microcomputer dimmer switch as needed for the surgery. The main operating light will then begin working. To increase the brightness from weak to strong or from dim to bright, press the upward triangle button; to decrease the brightness from strong to weak or from bright to dim, press the downward triangle button.
2. Rotate the focusing handle to adjust the spot size and depth of focus to achieve optimal illumination of the surgical site.
3. During operation, if the main light indicator light goes out while the auxiliary light indicator light illuminates (red alarm), the main light has burned out, and the auxiliary light is still working (due to the automatic power switching device). After the surgery, replace the bulb promptly, ensuring the main light is always operational while the auxiliary light remains on standby.
4. After each use, reduce the operating light brightness to its lowest setting and turn off the switch for future adjustments.
